' yhasbeen found particularly applicable for use in connection ,withv metal cabinets, such as are employed-- i-n. electrical installations, for housingpanelboardsand switchboards.

AnL object,` of my invention is-to provide an improved lock, wherein the bolt. is nor-` mally disposed. in locking. position, 'and' which is adapted to-yieldto-permit theclosing. and llatchingy ofthe door to which it is secured, and havin'ga loclingmemberY whichH cooperates with a bolt actuating lever, but is independentof the bolt itself'. This construction permits of the use of my device-f in' installations where-a simple spring,- door latch is -suficient VAnother object of the invention.` is that ofr providing a boltf releasing member whichis substantially flat and adapted to lie-close:

to, or withinl a recess in, thel door front. Knobs anda-other formsof actuating memberswhich project from the-face-of the doorare easilybrokenand rendered inoperative,l

afaultwhich thed'eviceof my invention tends to eliminate..

Another and further object of the present invention lies the-provisionof limproved means for mounting my device on ai door, the means enabling readyk removal and replacement. of the lock in event ofk damage thereto7 andfurther enables-the application, during manufacture, of any one of severalv types of lock to afV standardnmoun-tingplate-V permanently securedto the door.

A- still' fur-ther object` is to provide-means for replaceably mountinga lock on a metall doorzrby means entirely on the-rear or concealed side of thefclosure. obvious that if screws, rivets or the like project through the door, unauthorized persons may gain access toa cabinet by cuttingY or drifting the holding members from the front of the doo-r.. The present construction eliminates-this possibility,

l Further objectsV and` advantages will :ippear from the4 followingA detailed, description and drawing.

It is, of course,v

The device herein shown and'described by way of illustration, is constructed to permitl the use offa locking mechanismof the tumbler or--barrel type. Since this mechanism forms no part ofthe present inventionits v515,.

internaloper-ationwill not be explained and the descriptionwof same will be confined to the-manner `inwh-ich it functions toactuate certainf other membersofthedevice. l

In--thedraw/ing,tFig. 1 is a: plan view; Fig,

the position of the. Y tumfbler mechanism is indicated bydottedlines. Fig. 4 is a side elevationof my device as it would'appear when secu-red toaV mounting plate carried by a. metal door front; andFig` 5fis a plan view which shows por-tions of the-lock ordinarily visiblefupon-.the front of aicabinet door'vvhen the lock is mounted in accordance with theA preferred arrangement.

`Referring now tothe drawing and particularly to Figs. l, 2 and `3, 9. indicates, generally,- ametal case, havingits-bottom 10, sides 11 and-ends 12ff'ormed preferably of a single piece of sheet material, as is-customary in. locks of the type herein described; j Projecting; outwardly from the upper margins of the sidewalls-and lying! in a plane parallel to the box; bottom,y I provide fastening lugs 13 which are-apertnred to-gaccommodate screws for the-purpose ofy fastening vthe lock to a door. A cover` plate 14 is adapted for securement tdt-he case bylneans of marginal proj ections 1'5-:which engage recesses formed in l the wall, portions of the case. The cover plate is provided with a pair of upstanding bearings or trunnions 16 through which a pin 17 is disposed'to form a pivot for a lever 18. The pin- 17 is preferably upset or riveted at each end, so that the handle is inseparably or lixedly attached to the lock body or case,

siii' aswell 'asfi-noperative relation to the-mechi' tion,.as hereinafterV appears, the lock includ-- mg the handle, may beattached to, Vor removed fromthed'oor, as an assembled unit'.k

, anism.4 According; to the present construc- Y forms an actuating handle and is used in lieu of the knob or handle customarily employed.

An arm 19 (F ig. 8) which forms part ofthe member 18, extends into the case through an opening 20 in the cover plate for engagement 15 with the bolt 21. This bolt, of usual form,

isA normally disposedl in :1noutermost position, being urged to this position by al spring 22. the interna-l portion 24;of the bolt, abut the 201 case walland limit the outward movement of the bolt. As will be best seen by reference to Fig. 3, when the bolt is locked against actuation, the arm 19 extends through and slightly beyond an opening 25 in the bolt portion 24,

2:5@ so that it is adapted to come into contact with an upturned lip portion 26 of a locking member 27. In unlocked position, it may be men# tioned that the lip 26 is moved out ofthe path of movement` of the lever arm 19, so that the 39-bolt may be Vdrawn into the case by action of -the lever 18. I g

The member 27 is adapted for actuation by means of the tumbler locking mechanism. T Vhen the proper key isl applied and turned 3tovelfect the locking of the device, the member 27 is caused'tobe moved into the position indicatedY by dotted lines in Fig.I 2, which brings the lip 26 into the path of the arm 19 and prevents any actuation of the lever 18 4Q to operate the bolt, as will be well understood by those skilled Vin the art. 1 f l By referring to Fig. v3, it will be observed that the opening 25' is sufficiently extended to permit endwise movement of the bolt even V:though the lever be held in locked position by Y the member 27. Thus it will be seen that my deviceserves asacatch lock, anda door equipped therewith, may be moved from open to closed position and thereafter remain` Qzlocked until the member 27 is key-actuated.

The tumbler mechanism hereinbefore mentioned is by Ypreference provided with a customary barrel-type key socket, indicated at 29, and I provide an outwardly projecting 55.fcylinder 30 secured to the cover plate 14, for the housing thereof. The ksocket 29 1n the present example is located directly under the actuating lever 18, which is apertured as shown in Figs. 1 and 5, to permit access to the rkey socket. K

' In the application of my lock to a metal cabinet door, `I provide a mounting plate 31, which is secured to the door by any suitable means, preferably 'by welding it thereto.

'This plate isy provided with threaded aper- ,handle or other lock part, before Vthe device Shoulders 23 (see Fig. 2) formed on tures in register with the apertures in the fastening lugs 13, as well as with apertures to accommodate the cylinder 30, handle, and hinge assembly for the handle, these members being adapted to extend through the openings in the plate 31 and throughopening similarly shaped and correspondingly 1ocated in the door. This arrangement obviates the prevailing necessity of removing a can be'applied to or removed from a door.

As will best appear from Fig. 5, in which the opening for trunnions 16 and the handle is sh own at 32, this opening is of sufficient area to permit passing the handle therethroughvas the assembled lock is applied to the plate 31 on the rear of the door. There is, of course, provided an opening in plate 31, the latter opening corresponding in size and location to the opening 82. These openings are of such size and so disposed that they are closed at the rear by the lock body or case. f

It is understood that the above description relates to a single executional embodiment of my invention, and that certain changesmay be made in the device'herein shown and described without departing from the full scope and intended spirit of the invention, as defined by the appended claims.
